The people of Sri Lanka are divided into ethnic groups whose conflicts have dominated public life since the nineteenth century. The two main characteristics that mark a person's ethnic heritage are language and religion, which intersect to create four major ethnic groups--the Sinhalese, the Tamils, the Muslims, and the Burghers (see fig. 6). Ethnic divisions are not based on race or physical appearance; some Sri Lankans claim to determine the ethnicity of a person by his facial characteristics or color, but in reality such premises are not provable. There is nothing in the languages or religious systems in Sri Lanka that officially promotes the social segregation of their adherents, but historical circumstances have favored one or more of the groups at different times, leading to hostility and competition for political and economic power.
